Environmentally friendly textile pigments: implementation of genome mining-based approach for the identification of new anthraquinone producers.

, 2023
It is estimated that 200,000 tons of synthetic pigments are lost in the effluents of the textile industry each year. Most of these dyes escape conventional wastewater treatments, resulting in adverse effects on the environment, such as ecotoxicity,

Raman spectroscopy of modern art : classification and identification of Azo-pigments

, 2000
Micro-Raman spectroscopy (MRS) is an important molecular spectroscopic technique for the non-destructive examination of objects of art. In this work, Raman spectra of a number of Ate-pigments are presented, which are important artists' pigments in ...

On the use of photobleaching to reduce fluorescence background in Raman spectroscopy to improve the reliability of pigment identification on painted textiles [PDF]

, 2006
Subjecting a specimen of red lead watercolour paint on silk to photobleaching was demonstrated to be a simple means by which to engineer a reduction in the magnitude of the fluorescent background that was approximately exponential with time, with a ...
